When to get your amp up graded caps ???

I think it is sometimes necessary to "downgrade" the amp when one feels unworthy of the high quality of the sound.

The ten-ten-ten rule applies here. If your amp is over ten years old, it's time to think about a recap. If it's another ten years old it's time to recap, no thinking about it. If it's yet another ten years old, think Russian Roulette, 3 chambers live in a six shooter.

Since the op just bought the amp, Breuninger.. How do you know it has not already been done? The automatic: "go spend money" seems a bit over the top? Having it checked by a competent tech, or by MAC, (which is certain to not just change them to get some cash in hand) is a worthwhile idea IF the op is really concerned. Otherwise it is not much of a problem.
Calling it like Russian Roulette is a little over the top dude.

Russian Roulette requires 1 live chamber, otherwise it's just too dangerous.

The consensus is that power supply electrolytic caps should at least be considered for replacement when they start to get up in age. But, that really is a generalization and it really depends on the source/quality of the parts. I know a current builder that looks for certain older parts, including electrolytic caps, because he likes what they do in his designs. I am thinking of getting a linestage from this builder, based on an in-home audition. None of the parts, including the electrolytic caps are any younger than 50 years old and some parts are much older.

Some of these parts, made by such companies as Western Electric, command quite high prices on the market today.
